I'm trying to remove one silly grey line from the Music Controls on the lockscreen. It's the one that intercepts the volume slider and play pause ect. buttons. I've looked around quite a bit and have not made any progress. I know it's very minimal but it bugs me a lot as I use the Music Controls quite often on the go.

Before my screenshot let me just say I'm NOT looking for [email protected]
I already know what it does. I'm looking for a different image and any help or suggestions would be very much appreciated
